MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 621,991, dated March28, 1899.

Application filed November 29, 1898. $erial No. 697,789. (No model.)

To (all whont it may concern:

Be it known that I, WVALTER L. CAYWOOD, a citizen of the United States,residing at Hume, in the county of Bates and State of Missouri, haveinvented certain new and useful Improvements in Music-Leaf Turners; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention has relation to musicleaf turners.

The object of the invention is to provide a device of this characterwhich will quickly turn the sheets of music sheet by sheet by thedepression of a lever and which when all the sheets have been turnedwill restore the sheets to their original position to permit of arepetition of the music.

With this object in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed, and particularly pointed out in the appended claim.

In the drawings, Figure 1 is a front view of myimproved sheet-musicturner, showing the spring-arms turned to the right and in position forengaging the sheets of music. Fig. 2 is an edge view. Fig. 3 is across-sectional View on the line X X of Fig.1, looking in the directionof the arrow.- Fig. 4.- is a detail per spective view of the inner endof one of the spring-arms removed; and Fig. 5 is an end View of theleaf-turning arms, showing the arrangements of their outer ends.

In the drawings, 1 denotes the base, which is preferably made of woodand which is adapted to be secured to a piano or organ by the clamp 2,which may be of any well-known or approved construction and which has anadjustable engagement with the base by a slot connection, so as to adaptthe holder to diiferout forms of pianos or organs.

3 denotes the sheet-music holder,which consists of two clamping -jawssemicircular in Secured above the upper end stair step order orindifferent horizontal planes. The tension of the springs is ex" ertedto swing these arms from right to left. 13 denotes a lock-bar connectedto said base by staples 14 and having an offset end 15, that projectsthrough an aperture 16 in the lower end of the casting and immediatelyin front of the inner ends of the arms when they are swung in theposition shown in Fig. 1.

. It is understood that the free ends of the spring-arms are adapted toengage the sheets of music, and the object is to turn one sheet at atime. To accomplish this, I provide means by which the upper end of thelockrod may be lowered a distance corresponding to the width of eachtransverse guideway, so that the spring-arms may be, beginning with theupper one, successively released to throw the sheet of music from oneside to the other when desired. To do this, I provide the lower end ofthe rod with the rack-bar 17 the teeth of which correspond in numberwith the spring-arms. To depress this rod tooth by tooth, no more and noless, I provide the lever 18, which is pivoted to the base or support,and provide a stop 19 for said lever, which limits its downward movementas well as its upward movement. This stop may be in the form of astaple, as shown in the drawings. The lever after each depression iselevated to its limit by a coil-spring 20. 21 de notes a device forswinging the spring-arms back to their normal position if it be desiredto repeat the piece of music. This device preferably consists of a rodjournaled in bean ings 22 to the edge of the base or support and havinga crank-arm 23, which is adapted to be swung into engagement with thespring arms, and by rotating this rod the spring arms will be swung fromleft to right, or to the position in which they are shown in Fig. 1.

24; denotes two angular spring-arms, the inner ends of which are pivotedto the back of the wooden base. The upwardly-extending ends of said armsare adapted to lie flat against the sheets of music that are not desiredto be used, so thatin shifting the sheets that are in use the suctionwill not draw over the sheets that are not desired to be used.

In operation by depressing the lever to its lowest limit of movement,which is the distance of but one tooth, on the rack-bar the upperspring-arm will be released and will swing the sheet of music with whichit is engaged from right to left. The lever when released will beelevated byits coil-spring and will engage the tooth immediately abovethat just acted upon. A second depression of the lever will release asecond spring-arm, and this operation continues until all the sheetshave been turned. it it is desired to repeat the piece of music, thespring-ari'n-returning device is operated, which will throw thespring-arms over to the right-hand side. The lock-rod is then elevatedin front of the springarms and will hold them in their return positionuntil they are disengaged by the operation of the lever.

llavin g thus described the invention, what is claimed, and desired tobe secured by Letters Patent, is-

In a music-leaf turner, the combination with the base or support, ofspring-actuated leaf-turning arms, means for releasing said arms, and. amusic-clamp consisting of two jaws semicircular in cross-section, hingedtogether, one section being provided with a screw-threaded aperture andthe other with a horizontal elongated aperture, and a setscrew extendingthrough the horizontal elongated aperture and engaging the walls of thescrew-threaded aperture, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
